Yes, the rules of chess are simpler, which is why all this happened many years ago for chess.

https://gwern.net/note/note#advanced-chess-obituary -- here is a reference about centuar/advanced chess. The source isn't perfect as the tournaments seem to have fizzled out 5-10 years ago as engines got better and it all became irrelevant. Sadly this means we don't have 100 games of GM+engine vs. engine in 2023 to truly settle it but I've been following this for a while and I have a high confidence that Stockfish_2023+human ~= Stockfish_2023.

I think closed vs open problems are not simply different in magnitude of difficulty but qualitatively different. When I'm programming most of the interesting things I work on don't have a clear correct answer or even a way of telling why a particular set of choices don't get traction.

I guess it's possible that just being "smarter" might in some cases get a better solution from a seeies of text prompts but that seems too vague an argument to hold much water for me.
